'7 Claims. (Cl. 21937) This invention pertains to oven cooking apparatusand more particularly to a surface receding or well type of cookerheating unit.

Apparatus of this class is well known in connection with electriccooking ovens, and there is provided in accordance with the presentimprovement, a deep well cooking apparatus wherein the heating plate andcertain elements of the supporting structure are rendered adjustable asto surface level so as to permit variations in the depth of cavity,whereby cooking vessels may be supported under variable conditions.

The primary object of the present invention is to provide a deep wellheating apparatus in which the heating unit is vertically adjustable inpredetermined incremental amounts to thereby assume variable levels withrespect to the top and bottom of the well.

Another object of the invention is to provide in a deep well cookingapparatus adjusting facilities for variably positioning the heating unitor plate at predetermined levels.

For a more comprehensive understanding of the invention, reference willnow be had to the particular details of construction described in thefollowing detailed specification taken in conjunction with theaccompanying drawings, where- Fig. 1 is a transverse sectional view witha part in elevation, of the electric oven structure according to thepresent invention, showing the apparatus applied, and the adjustableheating plate thereof in its lowermost submerged level;

Fig. 2 is an elevational view similar to Fig. 1 but illustrating theheating plate raised to an intermediate level;

Fig. 3 is a top view of the electric oven structure according to thepresent invention;

Fig. 4 is a fragmental perspective view of the flange and handlestructure of the heating plate supporting frame;

Fig. 5 is a side elevation of the deep well oven structure featured inFigs. 1 and 2 showing an intermediate condition of operation;

Fig. 6 is a side elevation of the same structure with the operation ofFig. 5 completed;

Fig. 7 is a detailed perspective view of one of the pressed-outdetenting and adjustment portions; and

Fig. 8 is a perspective viewof the spider ring 2| with its integrallatch projections.

Having reference now more particularly to the accompanying drawing, thereference character I l designates the table top of a conventional typeof cooking stove or oven having a recess defined by a downwardlyextending flange 12. A cylindrical sleeve 13 is adapted to be receivedwithin the opening defined by the cylindrical wall I2 of the oven.Secured to the upper edge or rim of the sleeve i3 is a brim portion l4adapted to overlie the adjacent edge of the table top H to thus supportin a depending manner the sleeve l3. To the lower edge of sleeve I3 issecured by welding or other suitable means, a bottom member 15 which isprovided with a central clean-out and vent opening at l6 generouslyproportioned to provide ample clearance for electric cable connection(not shown) which may be attached to the heating plate unit generallydesignated I'l.

Sleeve I3 is provided with three vertical slots I8, preferably equallyspaced around the circumference of the sleeve l3, and extendingsubstantially the full height of the sleeve as best indicated in Figs.1, 5 and 6. Slots l8 are provided along corresponding edges thereof witha series of downwardly and diagonally directed seating notches l9.

Adapted to support an adjustable heating unit I1 is a spider ring 2|provided with three integral prong-like projections 22. Prongs 22cooperate with notches 19 to control the elevation or level to which theheating unit I! is adjusted to afford variation in depth of cavity,whereby cooking vessels may be supported under variable conditionsaccordingly.

An elevator generally designated 23 is provided to raise and lower thering 21' to adjust the surface level of the heating unit ll. The

. elevator 23 comprises an upper ring 24 and a lower ring 25 spacedapart a predetermined distance, commensurate with the depth of thecavity or well formed by the sleeve l3, by a plurality of pairs of rods26, equal in number to the number of prongs 22. The rods 26 and rings 24and 25 are preferably integrally connected together by welding, althoughany mode of securement may be used.

The rods 26 of each pair are, in turn, spaced apart to provide a trackor guideway 21 for the prongs 22. Spanning each guideway 21 andpositioned adjacent to the ring 25 is a crossbar or abutment 28 adaptedto engage the prong 22 when the elevator is manipulated. Attached to thering 24 by means of a plurality of clamping elements 29 is a rim portion3| of sufficient width to overlap the brim l4 and top ll of the stove.

The rim flange or cover ring 3i is provided at two diametrically opposedpoints with ear facilities 38 for mounting a pair of handles 32, saidfacilities including also nesting grooves 33 so conformed as to allowthe handles 32 to lie substantially flush With the surface of the rim3|. The sleeve I3 is provided around the upper portion thereof withpressed-out portions 35 which wipe against the flange l2 to retain thesleeve frictionally and compensate for the clearance between sleeve I3and Well l2.

During use of the deep well cooker, according to the present invention,the sleeve I3 is disposed within the well or recess defined by the wall2 with the brim l4 resting upon the stove top H. The elevator 23 isdepressed and Within the sleeve portion 13. Through the instrumentalityof handles 32 the framework or elevator 23 is raised and lowered, andwhen the prongs 22 are in register with any one of the notches theframework 23 is rotated counterclockwise sufliciently to bring all ofthe prongs 22 into the then adjacent notches [9, which level isdetermined, for example, by the height of the cooking vessel to beplaced upon the heating unit ll. Thereafter the framework or elevator isagain dropped into the position indicated in Fig. 6 as the spider ring21 holds the heat unit I! in its adjusted position.

Although a specific embodiment of the invention has been shown anddescribed, it is understood that such modifications are contemplatedwhich come within the purview of the appended claims.

What is claimed is:

1. In an adjustable level surface heater for cooking ranges, anoutermost cylindrical jacket supported in total submergence from thetable top of a range and having a plurality of vertical slots equallyspaced circuinferentially, each slot having a series of laterallyextending ledge supports in communication therewith, a heating unit, acylinder-like member nested within said jacket and surrounding saidheating unit including manipulation means disposed at said table topsurface, a support for said heating unit including extremities extendinginto said vertical slots and receivable upon said ledge supports, saidextremities being engageable by said cylinderlike member whereby to belifted to different levels and rotated into engagement with said ledgesupports, said cylinder-like member including portions having verticalclearance about their engagements with said support extremities so as tobe submergible after each variable level placement of said heating unitand its said support.

2. The combination set forth in claim 1 in which said manipulator meanscomprises a ring member having pivotable handles that may be held erector be made to lie prone so as to be out of interference with saidheating unit during table top surface level adjustment thereof.

3. The combination set forth in claim 1 in which said cylinder-likemember is outlined in metal wire defining said vertical clearanceportions.

4. The combination set forth in claim 1 in which said vertical slots insaid cylindrical jacket are three in number and in which said supportextremities are correspondingly three in number, one for each of saidslots.

5. The combination set forth in claim 1 in which said ledge supports areformed by sidewardly and downwardly extending notches communicating atdifferent levels with said vertical slots in said cylindrical jacket.

6. The combination set forth in claim 1 in which said cylindrical jacketis formed with incised and outwardly distented tabs adapted to havefrictional impingement against skirting flanges of a table top opening.

7. The combination set forth in claim 1 in which said heating unitsupport is an annular wire ring to which are welded L-shaped extensionswhich comprise said extending extremities.
